T0 all wwn't'it m/cty concern:

Beit known that I, CHRISTIAN .FRED EBEE- HARD, a citizen of the UnitedStates, residing at Cleveland, Cuyahoga county, State of Ohio, haveinvented certain new and useful Improvements in Ball-Bearings, of whichthe following is a specification.

My invention relates to ball-bearings for the wheels of carriages,Wagons, bicycles, and other vehicles and its object is lto provide animproved construction of the same which shall possess superioradvantages with respect to efficiency in use.

The invention consists in the novel construction and combination ofparts hereinafter fully described and claimed. y

In the accompanying drawings, Figure lis a central longitudinal sectionof wheel-hub and connections constructed in accordance with myinvention. Fig. 2 is a transverse section on the line :n Fig. 1. Figs. 3and 4 are similar views on the lines y y and z e, respectively.

In the said drawings the reference-numeral l designates a vehicle-hubformed with a central bore and screw-threaded interiorly at each end,and engaging with said screwthreaded ends are screw-capss 2, through oneof which the spindle hereinafter described passes. Alsoconnected withthe inner ends of the screw-threaded bore are correspondinglythreadedrings 3, the inner surfaces of which are formed with grooves or races 5,in which are seated balls 6. These balls bear against cones 7, securedto a sleeve 8, keyed to the spindle 9.A This spindle at one end isprovided with a screw-cap 10,'while at the other sani No. 541,552. onman.)

end it is formed with an enlargement 12 and withco'llar's 13 and 14.Bearing against each of said rings is a washer l5, consisting of a ringhaving a plain periphery and provided with a lug 16, which engages witha longitudinal groove 17 in the wheel-hub. Bearing against these washersare jam-nuts 18. By this construction the rings 3 may be adjusted withrespect to the cones and be securelyheld in position by the washers andj am nuts.

' Formed centrally in the hub l is an annu-Y laroil-chamber 19, having ailling-opening closed by aV plug `2O and provided with in @linedpassages 21.

By my invention the friction will be greatly reduced, and theconstruction generally is such that the invention will be found veryeffi? cient in use.

Having thus fully described my invention,

what I claim is-.

The combination with the hub having a screw-threaded bore and alongitudinal groove at each end, the screw-threaded caps, the

screw-threaded rings formed with grooves orraces, the washers havinglugs engaging the grooves in said hub, and the jam-nuts, of the spindle,the sleeve, the cones andthe balls"6'5 seated in the races in said ringsand bearing against the cones, substantially as described. In testimonywhereof l have signed my name to this specification in the presence oftwo subscribing witnesses.
